Is it possible to hide a category from general customers - but make it visible to groups with this? I'm wanting a way to hide Consultant supplies from the general customers, but make them available for purchase to my Consultants. I have the Consultants set up for group pricing.

Here is the site I'm working on:
http://www.undertherainbow-gifts.com

I want the Consultants and Distributors to be able to view and purchase marketing and sales supplies without the general customers seeing it.
